Kerry Cordero

Sr Network Architect

I have been in the IT industry for 15+ years. In the beginning, I decided while I was in college to get my MCSE and CCNA. I knew I needed these to get started. I was the youngest person in the class when I took a couple MCSE courses. I was in my teens when I got my NT4.0 MCSE. This exam at the time was HOT. I met people making 100k+ with their MCSE and experience. I also got my CCNA around the same time. For awhile I was doing both Microsoft and Cisco work. I ended up getting my MCSE 2003 and CCNP along with the Cisco Specialist Firewall and VPN cert years later. I started to do more and more Cisco work and loved it. I found myself going Cisco full time. I have been doing Network Engineering work for 10+ years now. I’ve been fortunate to work for and gain great experience with large Fortune 500 companies like FPL (15k+ Employees) & Kintetsu World Express (World Wide 10k+ Employees). I’ve also worked for companies like BE Aerospace (Fortune 1000 / World Wide 10k+ Employees), Broward County (10k+ Employees), Raymond James Financial (Fortune 1000 / 10k+ Employees), Sandals/Beaches Resorts (10k+ Employees), & Shriners Hospitals for Children (10k+ Employees).  Working for Sandals/Beaches also included responsibilities for more than 5 other companies.  Currently I am working for Progressive Insurance (10k+ Employees) as their Lead IT Systems Engineer.
